Soap Bubble ShapesAdd to list Details
Learners explore three-dimensional geometric frames including cubes and tetrahedrons, as they create bubble wands with pipe cleaners and drinking straws.
Fill It Up
Players take turns adding shapes made of three squares to a grid. They try to fit their shapes on the grid in a way that blocks the other player.
Touch the Spring (Lightbulb)Add to list Details
In this activity, a lightbulb is placed in front of a concave mirror. The actual lightbulb is not visible to the viewer, but the viewer can see the mirror image of the lightbulb formed in space.
Spherical ReflectionsAdd to list Details
In this art meets science activity, learners pack silver, ball-shaped ornaments in a single layer in a box to create an array of spherical reflectors.
PupilAdd to list Details
In this activity, learners explore their eye pupils and how they change.
Mirrors and ImagesAdd to list Details
In this optics activity, learners explore how many objects they can see in a set of mirrors (hinged like a book) at various angles.
In this activity, learners use an old CD to construct a spectroscope, a device that separates light into its component colors.
Reflecting Rainbows: Decorate Your White Walls With Rainbow Colors!Add to list Details
Like water drops in falling rain, a CD separates white light into all the colors that make it up.
Water Illusions: Refraction & Magnification
Learners demonstrate how water can distort, refract and magnify light.
In this activity, learners explore how nanosized structures can create brilliant color.
What is Nanotechnology?Add to list Details
In this activity related to nanotechnology, learners observe some of the effects that result from creating a thin layer of material several nanometers thick.
Pinhole ViewerAdd to list Details
In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.
Earth's Energy Cycle: Albedo
In this activity, learners experiment and observe how the color of materials that cover the Earth affects the amounts of sunlight our planet absorbs.
Cylindrical MirrorAdd to list Details
In this activity, learners create a cylindrical mirror to see themselves as others see them.
This is a great activity about wave interference. Learners will create their own wave machine and discover wave properties through hands-on investigation.
Magic WandAdd to list Details
In this activity about light and perception, learners create pictures in thin air.
Beyond Dominoes: PolyominoesAdd to list Details
In this activity, learners add squares to paper dominoes to make polyominoes.
Polarized LightAdd to list Details
In this optics activity, learners experiment with polarizers (small dark rectangles) to examine light intensity.
Hot SpotAdd to list Details
In this activity, learners explore the invisible infrared radiation from an electric heater.
Look Into InfinityAdd to list Details
Learners use two mirrors to explore how images of images of images can repeat forever.
